  1. A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyse a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly. Specialization is for insects. -Robert A. Heinlein

  2. When, where, how and why the academy should develop a closer relationship with the marine industry? Inaugural lecture - Professor of the Practice Bengt Ramne Chalmers University of TechnologyDepartment of Shipping and Marine TechnologyDivision of Marine DesignGothenburg, Sweden

  3. …. butfirst a completely different question • Whoam I?

  4. The academy should develop a closer relationship with the marine industry • Why? • Evolve or die! • Enhance the competiveness of the marine industry • Reduce the environmental impact • Feed back from the industry to identify area of relevance • Contribute to a broader knowledge-base for students and researchers • How? • Create applied development projects • Where? • What about here? • When? • What about now?

  14. Wärtsilä RT-flex50DF Two stroke low pressure gas (methanol) engine

  15. Engine-fuelpossibilitiestoconsider • DME (diesel) • Gas/Methanol-Diesel (diesel) • Spark ignition (otto) • Dual Fuel – (otto /diesel) • Two stroke high pressure LGI (diesel) • Two stroke low pressure (otto) • Partial premix combustion (otto/diesel) • Ignition enhancer

  16. Applieddevelopment projects fuel and engine technology • Alternative fuelled marine engines • Development and evaluation of alternative engine technologies • Development and evaluation of components like fuel pumps, injection valves, glow plugs etc. • Development of retrofit kits for existing engines • Gas based marine fuels – especially methanol • Development of the fuels as such with regards to ignition properties, lubrication ability, safety aspects etc • Alternative fuel – sustainably produced • Improved production methods out of a wide range of feedstock. • Carbon Capture and Recycling • Methanol produced out of fossil free produced hydrogen and captured carbon dioxide • Life cycle analysis

  17. Applieddevelopment projects • Engines and fuels • Energy efficiency, saving, recovery and conversion

  18. Efficiency - priorities • Logistic system • Utilization of ship • Selection of main parameters • Capacity and speed • Cargo handling • Time in port, speed at sea • Operation routines • Speed profile, weather routing • Hull shape • Propeller size and propeller design • Main engine selection • Energy preservation and recovery Imperfection at a higher level can never be fully compensated by perfection at a lower level

  41. Why now is a good time to get started • The need is great • Upcoming emission rules • Increased fuel cost • Actions are desperately need to get on track to the 2020 and 2050 environmental targets • EU and the Swedish Government has acknowledge the need to support development in the marine sector • TEN-T • Horizon 2020 • Strategiskainnovationsområde (SIO) • The Swedish Shipowners Association has a compiled a long list of urgent projects

  42. Which project to get started with?
